I bought the gun in august and in october I went to a TWAT game where the gun started acting up out of no where. The gun would shoot a bb about 20 feet and then just drop to the ground. Their gun tech took a look at my gun and discovered that the upper gearbox was leaking giving the gun basically little to no compression. He lubed it up and stretched out the seals which got me going for the rest of the day. It was working just fine until about 3 weeks ago and the same thing started happening. So I bought a whole new cylinder set (Modify) as well as a tightbore barrel, hop-up bucking and a SCS. I installed all of the parts and it was shooting great when i tested it out the first time, however I tested the gun again and it is shooting the 10 - 20ft it was before.

Now I took the upper gearbox out of the gun and tested the compression and the thing does not have the slightest leak.

So does anyone have any idea what could be doing this?
